             Summary: Make trident Kafka Spout log its assigned partition 
                 Key: STORM-2530
                 URL: https://issues.apache.org/jira/browse/STORM-2530
             Project: Apache Storm
          Issue Type: Task
          Components: storm-kafka, storm-kafka-client
            Reporter: Srishty Agrawal
            Priority: Minor


On using storm-kafka KafkaSpout, the generated worker logs have information about the task index rather than task ID while printing the assigned kafka partitions. It is difficult to fetch the executor ID reading a particular kafka partition if only task index is present in the logs.

[Example from generated worker.log while using storm-kafka module's KafkaSpout|https://gist.github.com/srishtyagrawal/e068bd934094d685a08ece5924e3e71f]. There were a total of 16 tasks and 2 executors assigned for this topology.
The executor IDs as indicated by storm-UI were (5 12) and (13 20). 

This problem has been eliminated in the KafkaSpout from storm-kafka-client module. Logs generated with the new KafkaSpout print the mapping between executor ID and the kafka parititions. The task ID is still not printed in the log line which prints this mapping.
